usually in a quadrilateral (four-sided shape) you multiply the height by width
In a triangle, the height by width then divide by 2. This is because a triangle is mathematically always half the area of the rectangle.
In a trapezium or trapezoid in some countries, its the top length added to the bottom length which is then divided by two multiplied by the length top to bottom. But always remember the height you multiply it with is the straight top to bottom length not the side length.
A=lw or a different formula depending on the object
A flat round object is a circle. Surface area of a circle = pi*radius squared.
how haout no
By integration, which basically means dividing the object into small pieces.
The question does not specify of what object the curved surface area is required. Without this information then a meaningful answer cannot be provided.

You cannot use surface area to calculate density. Density is a calculation comparing TOTAL area and weight of an object. In short you must use the total volume of the object when calculating the density.
You calculate the area of each face and sum them. Sometimes, some of the faces may be congruent and tat will save on the slog.
The formula to calculate the area of a triangle is 1/2 * base * height. To understand this, think of a rectangle or a square. To calculate the area of this object you would use length * width (which is the same as base * height). If you cut this object in half, you get a triangle. So that area of any triangle is 1/2 * base * height. I cannot answer your question because you are missing the triangle's height but you should be able to use the formula above to calculate the answer on your own.
To calculate the area of a space, first, you need a ruler or tape measurer. Next, measure the length and the width of the object, but not the height. Then, multiply the width by the length (or vice versa), and there's your answer. The answer would be in the unit of measurement squared.
